Appflication filed February 12, 1920, Serial No. 358,094/ Renewed June 7, 1923. i

which the following description, in connec-' tion with the accompanyingdrawingsfls a' specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for operating upon heels and particularly to machines for shaping the breast faces of French or Louis heels. I

The breast faces of French and Louis heels are curved longitudinally of the heel, a portion at the base of the breast extending forwardly of the shoe along the shank. T he forward edges of the base portions of such heels must be made convexto correspond be flush therewith. The breast proper of such heels, that is, the portion lying between the base portion and the tread face of the heel, is frequently curved transversely of the breast and is usually concave. Frequently, too, the portion of the breast adjacent to the toplift is concaved to a greater extent than the breast proper and at a less angle to the tread face of the toplift, the formation of this portion being known as scalloping.

An object of the present invention is to provide a machine by which the above defined portions of the heel may be formed in f the desired manner by a single operation and upon the same cutter.

A feature of the invention consistsin an organization comprising a rotary cutter and a shoe support arranged for relative movement to cause the cutter to traverse the heel from side to side of the heel with means for effecting, during said relative movement, another relative movement in such manner as to cause the cutter to form a convex face on one portion of the breast face of the heel of the shoe and simultaneously to concave another portion of the heel breast. As shown herein the cutter is ellipsoidal or egg shaped and rotates about a fixed longitudinal axis, the second relative movement as to vary the extent of the portion of the heel breast which is, convexed relatively to the extent of the portion which is concaved.

Another feature of the invention consists in means for varying the extent of said-axial movement, this adjustment causing the amount of curvature of the convexed and concaved portions of the heel breast to be varied, and particularly, causing the curvature of the convexed portion to correspond to the varying convex curves of the shanks p of different shoes. with. the transverse curve of the shanks and j A further important feature of the invention consists in an organization by which the relative predetermined position of the =heel and cutter for breasting may be changed to a relative predetermined position of the heel and cutter for effecting by said cutter a scalloping of the topliftof the heel, the change as shown being effected. -manually by a treadle.

In the illustrated construction the shoe, when positioned for the scalloping operation, is turned about the before-mentioned axis to cause the scalloping operation to be effected, the amount of turning movement being adjustably limited.

These and other features of the invention will appear more fully from the following detailed description when read in connection withthe accompanying drawingsand will be pointed out in the appended claims.

Referring to Fig. 1 of the drawings, the numeral 2 indicates the column of the machine upon which is a head frame 4- provided with bearings 6, 6 for a shaft 8 having between the bearings 6 a driving pulley 10 belted to a largepulley 12 having a shaft 14 journaled in bearings located near the base of the machine and driven from any suitable source of power. In the left-hand end of the shaft8 (Figs. f1 and 2) is a threaded socket 16Jadapted to receive the threaded end of a cutter member 18 having cutting edges which extend from the axis of the cutter at its end along the sides of the cutter' and are arranged to trace, as the cutter rotates, an egg-shaped body. The cutter accordinglylwill be referred to herein as eggshaped or ellipsoidal.

The work support includes a frame member 22 rising vertically from which are a bracket 21, carrying a plate25 toengage the tread 'faceof the heel, and a rest 26 to receive'tl1e.treacl face'of the forepart of the shoe. The plate 25 is on a block 24 which'is adjustably secured to a rearward projection 30 of the bracket 21'by a slotand bolt connection at'23; On the plate 25 is a stop for the rear end of the heel comprising a plate 34 having a V-shaped notch in its end to receive and center the rear part of the heel and to determine the longitudinal position of the shoe. The plate 34 is adjustable loi'i'gitudinally of the shoe by means of a screw 36 t'hreade'd through a lug on the plate'34 and ro'tatably held in an ear 38 formed on the plate 25, a thumb head 40 being provided to enable the screw to be "turned conveniently. Projecting through slots in the tread rest 26 are two stops 42, 4.4 which are connected together for equal and opposite adjustment by a right and left threaded screw 46 journaled in an ear 48 on the rear sideof the rest 26, a thumb head 50 being provided on the screw 46 to enable the stops 42, 44 to be adjusted toward and from eaeh other. The frame 22 is provided with hand holes 52, 54 into which the operator may insert his fingers while he uses his thumbs to press the last and shoe against the tread plate 25 and forepart rest 26 to hold the shoe in position to be operated upon. If the operator finds it more convenient he may, instead of putting his fingers through the holes 52, 54, grasp the portions of the Work support which contain these holes in other ways, for instance by closing his fingers on the part at the rear of the holes.

The frame 22 is provided with a cylindrical hub portion 55 which is embraced by a two-part bearing 56, 58 on the end of a link 60, the opposite end of which is pinned to a vertical shaft 62 which forms a pivot for it. The two parts 56, 58 of the bearing are held together in bearing engagement with the hub of the frame 22 by screws 64. The

cal portion 55, engaged by the bearing 56,

58, is a portion 7 0 formed with a segmental T-guideway which is engaged by a T-head 72 fixed to the upper end of a vertical h'ollow shaft 74. The shaft 74 is journale'd in bearings 7 6, 78 and arranged also for longitudinal movement therein. The bearings '76, 78 are connected by a rigid web 80 and are provided with arms 82, 84. I The arm 82 of the upper bearing 76 is pivoted by a screw 86 to the slide 69 and the lower arm84is pivoted to an ear 88 formed on a depending portion 90 of the slide 69. The pivot of the arm 84 is formed by the upper end of a shaft 92 which passes through the arm 84 and is threaded into the ear 88, theshaft being in vertical alinement with the pivot 86. It will be seen that the bearings 7 6, 7 8 connected by the web 80 are movable about a vertical axis passing through the pivots '86, 92. Thecurvature of the T-head 72'and 'gui'deway -is struck from the pivot 86 as a center. The position of the bearings about thisnxis is adjustably determined at the will of the operator by a spring pin 94 mounted in-an extension 96 of the arm 82 beyofnd its-pivot 86, the spring pin 94 beingarranged to engage any one of a series'of holes 89' formedin a projection 100 of the slide'69. By 'lift-' ing the spring pin 94 by its knob 95 the op erator may swing the extension 96 in either direction and cause movement of the bearings 76, 78 in the opposite direction about the vertical axis 86 and may place the" axis of the shaft 74 either in alinement with the axis of the hub 55 of the frame 22 or at either side of that axis for a purpose to be explained hereinafter, it being assumed for the present that the hub 55 and shaft 74 are in alinement.

A lower portion 154 of the hollow shaft 74 is of reduced size and encloses a rod 155 which is connected at its lower end by a ball and socket joint to a rod 104 which is connected to a treadle 106 pivoted at 108, so that depression of the treadle 106 will effect upward movement of the rod 155 and, by reason of an enlargement 157 of the rod 155 which engages the lower end of the portion 154, will effect upward movement of the shaft 74, 154, and with it the upward movement of the shoe supporting frame 22 to cause the cutter to traverse the shoe from side to side of the heel. The shoe, however, is free to turn about the axis of the shaft 74 and its movement about that axis is controlled by mechanism now to be described.

On the web 80 between the bearings 76, 7 8 is mounted an adjustable cam 110 (Fig. 3) which may comprise one or more leaf springs, the ends of which are held in a recess 112 formed in the inner face of a block 114 secured at 116 to the web 80. The cam 110 is engaged centrally of its inner faceby a screw 120 threaded through the block 114 and provided with a capstan head 121. By means 'of the screw 120 the springs of the cam 110 are forced to a greater or less extent through an open side of the recess 112, the

springs or cam 110 then being in the path of a roll 122 mounted on a collar 124 (Fig. 2) fixed by a pin 125 to a rod 127 inside the hollow shaft 74; The lower end of the rod 127 rests on the upper end of the rod 155 so that when the treadle 106 is operated the shaft 74, rods 155 and 127, and collar 124 with its roll 122, are raised together as a unit, the pin 125 engaging the upper end of the slot 129 in the hollow shaft 74, the pin lying in a slot 129 in the hollow shaft 74 to permit movement of the shaft relatively to the pin, collar 124 and rod 127, for a purpose which will later appear. Surrounding the shaft 74 is a combined compression and torsion spring 126 which is secured at one end to the collar 124 and at the other end to a collar 128 loose on the shaft 74 and having teeth on its upper face to engage corresponding teeth formed on the bearing 76. The torsional tension on the spring 126 tends to turn the shaft 74 and the shoe support to hold the roll 122 against a face 130 of the block 114 and cam 110. The tension of the spring 126 may be varied by turning the collar 128 which is provided with capstan holes for this purpose.

When the treadle 106 is depressed to move the shaft 74 longitudinally its movement will be opposed by the spring 126 which acts as a return spring for the shoe support, and during its longitudinal vertical movement the roll 122 will at first engage the face 130 of the block 114 (Fig. 3) as explained. When the shoe has reached a point such that the heel is about to be engaged by the cutter the roll 122 will reach the cam 110. As the vertical movement of-the shaft 74 continues the roll 122 will be moved to the left by engagement with the cam 110 and hence the shaft 74 will be turned at first in a clockwise direction against the spring 126, and then will be turned by the spring in an opposite or counter-clockwise direction as the roll 122 passes the top of the cam 110, carrying with it, of course, the'shoe support and shoe. Referring to F 1g. 4, it will be seen that the cam 110 causes a rocking movement of the shoe about the center of the hub 05 which coincides, in the position shown, with the axis of the shaft 74, and that, therefore, as the shoe passes the cuttersaid rocking movement will cause the portion of the breast adjacent to the toplift to be concaved, the depth of the concavity diminishing from the tread face toward the axis 55. At the same time the base portion of the heel which extends along the shank will be moved first away from the cutter and then toward it, so that in conjunction with the movement of the heel about the axis 55 tocause the breast to be concaved, there will be corresponding movement of the base portion of the heel first away from and then toward the cutter to cause the base portion of the heel to be formed with a convex curvature corresponding to the curve of the shank. The shape of the heel breast resulting from the operation of the machine as described is shown in Fig. 7. The portion of the breast at a is convex, the convexity diminishing from the shank line dcZ, where it coincides with the curvature of the shank, toward the line 6-5, and the portion 0 of the breast is concave, the concavity increasing from the line 21-?) toward the tread face of the heel. At the line bb the breast is substantially straight transversely of the heel.

The movement of the shoe and the result-- ing operations of the cutter upon the shoe may be varied and modified to adapt the machine for different conditions of work by changing the location of the axis of the shaft 7 4 with relation to the axis of the hub 55 on which the shoe support and frame 22 turn. This is effected, in the construction described, by releasing the spring pin 94 and turning the extension 96 on the axis 86 to vary the position of the shaft 74 'eccentrically with. the axis of the hub 55. From Fig. 6 it will be seen that the T-head guide 70 formed on .plane of the tread face of the heel.

will cause no displacement of the hub 55 and the work support. When, however, the work support is raised after this; eccentric adjustment has been made, rocking ofthe shaft 74 by the earn 110 will effect move ment of the shoe support about a differently located center which center, by the adjustment described, may assume various positions between the plane of the heel seat and the plane of the toplift. This results in vary-,

ingthe area of the heel which is convexed relatively to the area concaved. Thus, with the pin 94 in the lasthole at the right (Fig.- 4) a greater portion of the breast surface would be concaved and less convexed, while with the pin 94 in the opposite extreme position, as shown in Figs. 8 and 9, the surface of the breast V-FOUlfl-bfi substantially allvcone vexedexcept the breast edge of the toplift .which would be substantially straight, as

shank can be varied of course by adjusting the cam 110 to vary the amount of turning movement.

In a machine organized asshown. herein, the operator may now, whileholding the shoe on the work support in the same position, perform the operation of forming in the toplift portion of the heel breasta more pronounced concavity or scallop. The work support, as described, is mounted on the slide 69. This slide extends transversely of the machine frame in a direction parallel with the shaft 8 and rollerbearings 140 are suitably arranged in. the frame to permit free movement of the slide 69 in a horizontal direction. In the rear face, of the depending portion of the slide 69 a T-way 142 (Fig. 5) is formed in which a-T-block 144 is arranged for vertical sliding movement. On the T-block 144is a cam face 146 (Figs. 2 and ll) and the T-block 144 is connected by a rod'148 to one end of a link 150, the other end ofwhich is pivoted on the shaft 92. A member 152 ,is arranged to slide'vertically on the shaft 92 and is formed to em brace the link 150 so that vertical movement of the member 152 compels vertical movement of the link 150 and hence of the T-block 144 and cam face 146.. The reduced lower end 154 of the shaft 74 passes freely through the member 152 and the shoulder formedby the reduction rests in the upper face of the member 152. The member 152 is connected'by a rod 156 with a treadle 158 arranged beside the treadle 106 and pivoted on the sameaxis 108. When the treadle 158 is depressed the member 152 islifted, carrying Withit the shaft 74 and, of course, the work support, and sliding on the shaft '92.- At the same. time movement is imparted through the rod 148 to the cam face 146' causing it to engage a roller 160ha-ving a fixed axis on the machine frame. W'Vhen the cam face reaches the roll 160 the slide 69 is moved outwardly of the machine frame against a tension spring 162 connected be tween the. frame and the depending portion 90 of the slide. Thismovement, of course, carries the shoe away from the cutter in the direction of the cutter axis. When sufficient vertical movement has been'imparted to the shoe to bring the center of the heel breast or the longitudinal median plane of the shoe into coincidence with the cutter axis, the member 152 engages anadjustable collar 164 on the shaft 92which limits further upward movement of the shoe. In order to cause the shoe heelto engagethe cutter it is necessary to turn the shoe 'and its support onthe shaft 74, and means is provided adjustably to limit this] turning movementso that the depth-of the scalloping cut may be controlled. Forthis purpose the collar 124'is' provided with a pro-- jection 166 (Fig. 5) which is ,in position to:

engage. a stop screw 168 threaded through the web 80 and is'provided with a thumb head 170.

During vertical movement of-the shoe for the scalloping operation it is desirable that] the cam roll 122 remain at rest; to give free .100

control of turning movement, for effecting the scalloping operation, to the operator and to avoid'any possible interference with 1 that movement by engagement of the cam roll122 with its cam In the constru0- 105 tion shown the; roll will remain at restrwhen the shoe is raised by the right hand treadle 158. This is because the lifting force is applied to the shaft-74 through the member 152 andthe rod 155 in the" lower part 154110 The spring 126 tends to hold'the block124 1.15

down during elevation of the shaft 74' for the scalloping operation. After the shoe has been elevated by operation of the treadle 158, as shown in Fig. 11, the shoe may be turned clockwise to bring the heelinto: en-

gagement with the cutter, as shown in Fig. 12 the depth of the out being limited by engagement of'the lug 166 with the screw 170. The adjustment of the screw is preferably such that the scallop extends from corner to corner of the heel breast, as illustrated in Fig. 13, which shows a heel after the breasting and scalloping operations have been performed. A compression spring 172 is provided on the shaft 74 between the member 1 152 and the arm 84 to insure return movement of the cam 146 when the treadle 158 is released after the scalloping operation. The amount of longitudinal movement of the slide 69 effected by vertical movement of the shoe support may be varied by means shown in Figs. 2 and 11 where it will be seen that the inner portion of the cam face 146 of the T-block 144 is formed on the upper ends of plates 145 which are slotted and are held in place on the T bloclr 144 by a screw 147 passing freely through the slots in the plates 145 and threaded into the block 144. By loosening the screw 147 one or more of the plates 145 may be moved downwardly out of operative relation to the roll 160 and hence the amount of movement of the shoe support lengthwise of the cutter shaft effected by upward movement of the block 144 may be varied with the result that the portion of the tread face of the heel adjacent to the toplift in which the scallop is made will be located opposite different portions of the cutter. Hence a portion of the cutter may be selected which is of the shape and diameter to produce the desired form of scallop upon the heel.
